E90 Service

i bought a E90 at Bmw worcester few months ago. after 2months the airbag light went on and the steering wheel making funny noise. I called Bmw worcester to sort this out. all they did is reset the airbag light. after 3weeks the same airbag light is on again. contact customer care Bmw. the car went in again for the same thing. they reset the airbag again for the second time. after few weeks light went on again i emailed customer care again and put my disappointment in the email. in this stage BMW WORCESTER closed they doors forever. Paarlberg Bmw contacted me for the airbag and the steering wheel noise. car went to Paarlberg they did diagnostic test on the car few problems pop up. i sent the quotation to customer care to ask who problem is this niw because i dont have the car that long now they telling me they cant take responsibility for Worcester bmw who sold me a broken car and never told me that. deeply disappointed with this. no one at paarlberg or Bmw south Africa want to take blame for WORCESTER thats closed.
